Application filed April 11, 1925. Serial. No. 22,279.

To all 'whom it may concern.'

Be it knownV` that I, JEAN FRANois GE- vnrnrs. a subjectief the King of Great'Britain, and a resident of Sudbury,v in the Provnice of Ontario, Canada, have invented certain new and useful Improvements 1n Butchers Block -Scrapers, and do hereby declare I that the following isa full, clear, and exact description of the same. v

.My invention relates to improvements 1n butchers block Scrapers, andmore particu- 'larly to a power-actuated scraper.`

' The object of my invention is to devise a scraper of simple form, easily manipulated, .very rigid, and effective in action.

To this purpose, I have shown in the accompanying drawings various views of this device and in every view, the saine letters of'reference refer to same parts throughout.

Figure 1 is a view of my scraper in working position on a butchers block;

.- Figure 2 is a front view thereof;

Figure' 3 is a central section;

Figure 4 is a detail showing how the scraping brushes are attached; and

Figure 5 is aview of the motor and the adjustable standard thereof. showing their relation with the butchers block.

Referring more particularly to Figure 5, 1 is a standard, here shown with three ,legs supported on' casters 2. 3 is an electric motor to whichis fastened a rod 4. This rod is slidingly mounted in the standard, which is hollow for that purpose. In order to adjust the height of the motor to the height of various butchers blocks, I provide a set screw 5 on the standard to hold the rod 4. 6 is a flexible shaft shown in broken sections,

casing 8 made in two sections, the rear face y9 -thereof forming a flange integral with the sleeve 10, covering the brush shaft 11 and serving as a hand-piece as well. This shaft is mounted in casing 10 in bearing 12 which, in the present instance, is in the form of a bushing retained in position by a set screw 13. Shaft 11 is provided outside lbearing 12 with an eye 14 into which the dexible shaft 6-is fastened. Shaft 11 also has a bushing 1,5 forming a bearing adjacent the flange 9. This bearing is kept in place by a set screw 16. "Onto the' shaft 11 adjacent the bearing 15 a brushl core 17 is mounted. 'This core is preferably fastened to shaft 11 by means of a key 18. The core is surmounted by a metal cylinder 19 formed in .sections and fastened the same by means of screws 2U. This sectional cylinder is perforated as at 21 to receive a plurality of steel bristles 22."

These bristles are mounted on the cylinder by passing through the' openings 21 land their inner ends are turned at right angle so thatthey rest against the brush core, as shown 1n Figure 4. It will be understood that such perforations' extend all around the cylinder and that a great number of steel bristles are mounted around the core 17.

The brush so constructed is enclosed in a casing 8, preferably made in one piece and having a handle 24 and a bearing 26 formed of a bushing 27 mounted in a projection rn the casing, this bearing being retained by i set screws 28. The casing 23 is fastened to flange 9 by means of thumb' screws 29. It will be understood that a section of `the periphery of the casing is open, as at 30, to allow the brush bristles to project'.` outside the same.

, In order .to regulate the contact of the 'bristles with the block, I provide a gauge 3l mounted in a bracket 32 on the casing. This bracket 32 is perforated to receive a bolt 33 which projects from the gauge 31. and intermediate same and the bracket a spring 34:l

is mounted. The bolt is threaded at its upper end and held in position by means of a nut 35. The opposite side of the gauge is hinged as at 36 to the casing, as shown in Figure 2. By this construction, the gauge is resilient and allows the bristles to more or less engage the block according to the pres. sure applied on the casing. l

Referring again to Figure' 5, it' will be seen that the motor is connected to the l scraper by means of a flexible shaft and that in order to dispose the motor to the right 'height according to the block to be scraped, it is adjustably mounted vertically as' heretofore explained.

In operation, the scraper is placed on the butchers block land the motor adjusted to the' height required. lThe operator holds the scraper by means of handle 24 and sleeve 10, and moves the same over the block, when the steel bristles will readily engage the block according to the pressure the operator places on the scraper and remove not only the accumulated material on the same but will act more or less as a planer to even its surface.

. When not in service, the machine may be stored away by using the handle 24 as a hanger.

` In the present showing, I have described one form of such scraper which has given Very good results but it should be understood that I reserve the right to any changes coming Within the scope of my invention and covered by the following claim: v

In a butchers block scraper of the class described, in combination, a motoxgmeans to adjust the height of said motor, a flexible shaft extending from said motor, a rotary scraper mounted on a shaft to which said flexible shaft is connected, a core on said shaft, sectional cylinders mounted on saidl core, a plurality of perforations in saidsectional cylinder, steel bristles mounted in said perforations having their inner ends bent at right angles so as to rest against the brush core, means to fasten said sectional cylinder on said core, a casing over said brush int which said shaft is mounted, an opening in said casing, a gauge surrounding said opening having one side hinged to the casing and the other having a bolt passing through a bracket in the casing, and a spring between the gauge and the bracket to cause the said gauge to move resiliently vertically.v

In testimony whereof, I have hereunto af fixed my signature, this 23rd day of July, 1924, at Sudbury, Ontario.

.JEAN FRANoIs GEVAERTS.
